Description
Technical field
The present invention relates to the motor vehicle that a kind of converter (inverter) drives rotating machine system, use therein whirler, converter and uses it.
Background technology
In recent years, with the energy-conservation target that turns to, in the variable-speed operation of whirler, be extensive use of inverter power supply.But, driving under the situation of whirler by inverter power supply, can produce the insulation degradation of the whirler that rapid surge voltage (surge voltage) that it is generally acknowledged because of converter causes.For converter surge voltage in this,,, took some countermeasures in whirler one side by the insulation of whirler inside being strengthened etc. in the past.
Yet, in recent years, in the Hybrid Vehicle inverter-driven rotating machine system, for with the further miniaturization of inverter-driven rotating machine system, high efficiency, the direct voltage that begins gradually to pay close attention to converter inside gives high-pressure trend, and promotes the system of the output density of inverter-driven rotating machine system with same size.In addition, in the future, not only engine being helped, is in the fuel cell car or electric automobile of main driving machine at whirler, in order to realize small-sized light weight, the high efficiency of inverter-driven rotating machine system, also further considers the possibility that realizes high-pressure trend.
But, if direct voltage high-pressure trend with converter, the surge voltage that the surge voltage that the high speed power semiconductors such as IGBT of converter inside produce when direct voltage is carried out ON/OFF and this surge voltage are amplified by the whirler end when transducer side arrives the whirler end also increases.
To these high voltage surges, strengthen if want the insulation that realizes whirler inside, can cause whirler to maximize.
Therefore, it is generally acknowledged except the insulation of whirler inside and strengthen that in the future, the whirler outside also needs to take method that surge voltage is suppressed.
Here, as method at the outside inhibition of whirler surge, for example known have: the means that the surge voltage amplification phenomenon of sine waveization filter or reactor (reactor) conduct inhibition cable (cable) and whirler is set at converter output terminal, relax the rise time of rapid surge voltage, the filter cell (for example non-patent literature 1) of the rapid voltage composition that absorbs surge voltage perhaps is set at the whirler end.
In addition, in recent years, a kind of cable (for example, patent documentation 1) that absorbs surge voltage has been proposed also.
[patent documentation 1] spy opens 2005-183654
[non-patent literature 1] GAMBICA/REMA:VARIABLE SPEED DRIVESAND MOTORS Motor Insualtion Voltage Stresses Under PWM InverterOperation:A GAMB ICA/REMA Technical Report No.1
Yet, as non-patent literature 1 is put down in writing, be connected in series between converter output and the whirler owing to be arranged at the filter of converter output terminal or reactor, therefore need to flow through main drive current diameter conductor or can be because of the saturated core sectional area of main drive current.Its result, the box sizes of these devices can be equal to converter and whirler or be bigger than it, the problem that exists inverter-driven rotating machine system to maximize.
In addition, as non-patent literature 1 is put down in writing, under the situation of the filter cell that the rotation pusher side is provided with the rapid voltage composition that absorbs surge voltage, because of the rapid voltage that absorbs can cause the unit heating, existence must be by large-scale fin etc. to its problem of dispelling the heat.
Have, the surge voltage of record absorbs in the cable in the patent documentation 1 again, generates heat owing to cable self absorbs surge voltage, has suppressed the conductor caloric value of the drive wire of cable, the drive current of therefore may having to suppress.In addition, be high resistant or open circuit because surge absorbs the end of line, so this end produce voltage.Therefore, in high resistance part or the open circuit end, must implement special insulation processing, may need that the cable of inverter-driven rotating machine system is installed the operating personnel and carry out maintenance, the guarantee that new special insulation technology instructs and carries out certain technical level.For problem in this, though can determine length of cable, the purchase of needs and use the cable of implementing special insulation processing in advance, but in the general industrial equipment, the machines configurations of installing the destination of inverter-driven rotating machine system, the size of cable pipeline, often be to block to length arbitrarily according to the cable that structure will be wound in roller (drum) to use, have the problem that the degree of freedom of installing the destination is caused restriction.Have again,,, may need the insulation processing portion of open end is taked the insulation degradation countermeasure or implement to safeguard because of the heating of cable self, on every side the situation of temperature, humidity, dust, salt, vibration etc. even after installing.

Here, on the cable C1, be connected with and append cable CA2, because both impedances are equal, therefore can be as the situation of not appending cable CA2, rotate the reflection in the machine end, voltage signal by path Xa arrives arrives resistance R through appending cable CA2, after the resistance R reflection, arrive the input of rear portion electric power generation machine RMG, this is path Xc.
Surge voltage is the situation of voltage V1, and the voltage of the input from path Xa to rear portion electric power generation machine RMG is V1.In addition, the voltage of input from path Xb to rear portion electric power generation machine RMG, by resistance R and the impedance dividing potential drop of appending cable CA2, for example, if establishing resistance R is 100 Ω, the impedance of appending cable CA2 is 50 Ω, then is (V1/3).If establishing cable CA1 equates with the propagation delay of appending cable CA2, then among the moment t1, from the overlapping signal that obtains of surge voltage of path Xa and path Xb transmission, as the signal appearance of voltage V2.Time (t2-t1), be cable CA1 and the propagation delay of appending cable CA2.Surge voltage V2 is V1+ (V1/3)=1.33V1.
Have, through the surge voltage V3 of path Xc, because at the input of resistance R, because of the impedance of the resistance value (100 Ω) of the impedance (50 Ω) of appending cable CA2 and resistance R does not match, and the reflected wave of generation V1/3 is (4/3) V1 again.In addition, because propagation delay occurs at moment t2.
The variation of the surge voltage of the whirler end when Fig. 3 represents that the resistance value with resistance R repeatedly changes.Voltage V2 by path Xa, Xb produce shown in the single-point line, reduces with resistance value R increase.By the voltage V3 that path Xc produces, shown in dotted line, increase with resistance value R.Because within voltage V2, the V3, a bigger side is maximum surge voltage, therefore as can be known, what allow maximum surge voltage minimum is, when cable CA1 and the impedance Z 0 of appending cable CA2 are made as 50 Ω, when the resistance value of resistance R is made as 100 Ω, the maximum surge voltage of this moment is (4/3) V1.
Not using under the situation of appending cable and resistance in the past, if establishing V1 is 300V, then the maximum of surge voltage is 600V, and is relative therewith, in the present embodiment, can be reduced to 400V.Therefore, for example, be 600V if establish the anti-surge voltage of rear portion electric power generation machine RMG, even then because with the direct voltage high-pressure trend to 1.5 of converter times, the whirler outside also can suppress surge voltage, does not therefore need the internal implementation insulation of whirler is strengthened, and just can improve insulating properties.
As mentioned above, because the voltage signal of the driving usefulness of the lower frequency that uses in the driving of rear portion electric power generation machine RMG, through path Xa, promptly offer rear portion electric power generation machine RMG through cable CA1, so the core of cable CA1 (core wire) is established slightlyer.For example, establishing sectional area is 14mm
